Needle roller bearing is one of the important parts for construction machinery, poor installation can affect their efficacy, or even engineering machinery and equipment failures. Where bearings are mounted on the after, if not carefully tuned, alignment can lead to bearing subjected to additional loads, friction and vibration. These might accelerate fatigue and reduced bearing service life, and may damage other parts of the machine age. In addition, increased vibration and friction can significantly increase the energy consumption and the risk of premature failure.
If bearing scrap iron, burrs, dust and other foreign bodies to enter, will cause the bearing in operation noise and vibration and may even damage the Raceway and the rolling. So before installing the bearings, you must ensure that the mounting surface and installation, clean environment.
Lubrication on the operation and life of the needle roller bearing has very important implications. Grease is made of base oils, thickeners and additives. Grease performance mainly decided by the base oil. Low viscosity base oil suitable for low temperature, high speed, high viscosity suitable for high-temperature, high-load.
Bearing lubrication performance thickening agent, thickening agent for water resistance water resistance of decides to grease. In principle, the different brand of lubricant cannot be mixed, and, even if it is the same the grease thickener, also brings bad influence because of different additives. Bearing coated with antirust oil, must carefully clean with clean gasoline or kerosene, then coated with clean high quality or high temperature lubricant for installation. Cleaning sealed bearings do not require oiling.
During use, frequently to monitor the basic external bearing running condition, such as temperature, vibration and noise measurement, and so on. These regular checks for early detection of potential problems and will prevent unexpected machine suspend, make the production a reality, improving factory productivity and efficiency.
During the operation, bearing requires proper lubrication once again, perfect its performance. Methods of needle roller bearings lubrication is divided into grease lubrication and oil lubrication. In order for the bearing play function very well, first of all, to select suitable for conditions of use, use of lubrication method. If you only consider the lubrication, lubricant oil lubrication of the dominant. Grease lubrication around bearing structure can be simplified like that.
